PUZZLE.

Application led January 23, 1908.

Specication of Letters Patent.

To all whom it may concern:

Be it known that I, ELDRED G. JENSEN, a citizen of the United States of America, and a resident of Medfield, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Puzzles, of which the following is a specilication.

This invention relates to puzzles and has for its object the production of such a toy which will be simple in construction and at the same time present a problem which will tax the ingenuity and skill of the operator to solve.

rI`he invention consists in certain novel features of construction and arrangement of parts which will be readily understood by reference to the description of the drawings and to the claims hereinafter given.

Of the drawings: Figure 1 represents a plan of a puzzle embodying the features of this invention. Fig. 2 represents a vertical section, the cutting plane being on line 22 on Fig. 1. Fig. 3 represents an inverted plan of the same, and Figs. 4 and 5 represent, respectively, a plan and an elevation of one of the movable slot-engaging members.

Similar characters designate like parts throughout the several figures of the drawin s.

In the drawings, 10 represents a plate of any suitable material and any desired thickness, the material used being preferably sheet metal which may be stamped by dies to form two circular depressions 11, the walls of which extend downwardly from the upper face of said plate, the depressions communicating with one another at one point.

A revoluble disk 12 is preferably secured by means of a rivet 1S to the raised portion 14: extending upwardly from the center of one of the cylindrical depressions 11 while a disk 15 is similarly secured by means of a rivet 16 to the upwardly extending boss 17 in the other cylindrical depression 11. Each of the disks 12 and 15 is provided with a plurality of sets of radial walls, each set consisting of a pair of walls, as, for instance, the walls of the slots 18, each set of walls extending to the edge of a disk and being adapted to retain a movable member. It is obvious that the sets of radial walls may be either those of a slot, as shown, or the walls of an equivalently acting projection on said disks without altering the principles of this invention.

In like manner the plate 10 is provided with a plurality of sets of radial walls, as, for instance, the walls of the slots 19 or the equivalent therefor. The slots 19 extend through the walls of the depressed chamber 11, as indicated at 2O (Fig. 8) and the walls thereof are adapted to retain a movable member. Each disk 12 and 15 is provided with the same number of radial slots 18 or the equivalent therefor and the plate surrounding each disk is provided with an equal number of radial slots 19. In the drawings the number of sets of radial walls in each of the disks is three but it is obvious that a greater number of sets may be used if desired, at the same time equally increasing the number of sets of radial walls in the surrounding plate 10.

For convenience of description each set of radial walls will be hereinafter referred to as the slots 18 and 19 of the disks 12 and 15 and the plate 10, respectively, although it is self evident that the disks and the plate may be provided equally as well with any other alternative means for retaining a suitable movable member 21 which is adapted to engage with the pair of walls of each of the slots 18 and 19 and be retained thereby in position.

All except one of the slots 18 and 19 is provided with a movable engaging member 21, the shank 22 of which is of such a diameter as to be freely movable in said slot-s 18 and 19. lVhen the disks 12 and 15 are moved about their pivots 18 and 16 and the slots 18 and 19 register, it is obvious that the slot'engagingmembers 21 may be moved from one slot to the other.

#Vhen a slot-engaging member is moved from a slot 19 to a slot 18 and the disk 12 or 15 containing said slot 18 is moved about its pivot the slot-engaging member 21 will be carried with said disk 12 or 15 about the pivot 13 or 1G to any point where the slot 18, in which said slot-engaging member 21 is held, will register with another slot 19 in the plate 10 or with one of the slots 18 in the adjoining disk 12 or 15 so that the slotengaging member 21 may be transferred into a new position.

As there are slot-engaging members 21 for all except one of the slots in the two disks 12 and 15 and the plate 10 to which the disks are pivoted, it is obvious that only one slot-engaging member 21 may be moved from one slot 18 or 19 to another at a time. The length of the slots 18 and 19 is such that the slot-engaging members 21 in these slots may pass each other when the disks 12 and 15 are moved about their pivots 13 and 16.

Six of the slot-engaging members are provided with suitable characters such as letters, these lettered members being located normally in the slots 18 of the disk 12 and the slots 19 in the plate 10 surrounding` said disk 12, these slot-engaging members 21 being located so that the various characters thereon will read consecutively, as A, B, C, D, E, F. In like manner the slot-engaging members 21 located in t-he slots 18 of the disk 15 and the slots 19 of the plate 10 surrounding said disk 15 are provided with characters such as numerals which are placed in the slot so as to read consecutively, as 1, 2, 3, 4, and 5.

The various slot-engaging members being thus located respectively in the slots 18 in the disks 12 and 15 and the other slots 19 in the plate 10, the problem is to so move about the disks 12 and 15 with the slot-engaging members 21 carried thereby as to move all of the lettered members 21 so that they will be located in the slots 18 of the disk 15 and the slots 19 surrounding said disk 15 in consecutive order and at the same time effect a movement of the numbered members 21 so that they will be transferred to the slots 18 in the disk 12 and the slots 19 in the plate 10 surrounding the disk 12 and be located therein in consecutive order.

While in the drawing the devices for retaining the movable members 21 are shown as slots 18 and 19 in the disks 12, 15, and the plate 10, respectively, it is obvious that other means may be provided in lieu thereof without affecting t-he principles of the invention. It is also evident that while to simplify the construction the disks 12, 15, are shown and described as mounted in depressions 11 in the plate 10, any construction may be used which will permit any one of the retaining devices of either of said disks to be brought into alinement with any one of the retaining devices of the other disk or into alinement with any one of the retaining devices on the plate 10 and surrounding the particular disk being operated. This makes a very interesting puzzle, presenting a problem which is capable of being solved but which requires considerable skill and ingenuity to do so.

It is believed that the invention will be thoroughly understood from the foregoing without any further description.

Having thus described my invention, l claim:
